GREASE CUP' FOR FLU'lD LUBRIGANTS.

Application filed May 1,

To aZZ 'whom t may concern: Be it known that EMiLE FIQUEREZ, acitizen ofthe Swiss Republic, residing at St. Ursanne, Switzerland, has inventedcertain new and useful Improvements in Grease Cups for FluidLubricants,. of which the following is a specification. Mylinventionrelates to a grease-cup for fluid lubricants in which the distributionof the lubricant may be very accurately regulated. In said grease-cup,the llubricant reaches the member to be lubricated through adistributing conduit into which the lubricant flows through a valve. Theopening of the said valve may be very accurately regulated, and itsposition indicated by operating an indicatingmeans locatedoutside thegrease-cup. The aforesaid valve is preferably positioned at thelo-wermost part of the apparatus so that full pressure from the liquidwithin the grease-cup may be exerted on the valve. Moreover, the body ofsaid grease-cup is made of a material commercially known as cervinitewhich is a substance not unlike Celluloid, being 'constituted ofcellulose and acetone, and which is transparent, practically unbreakableand uninflaminable. The result is that the greasecup will stand shocks;will be of light weight, will have a pleasing appearance and will permitcontrolling at anyvmoment of the quantity of grease fed therefrom.lBesides, the quantity of lubricant actually reaching the member to belubricated may be observed through the distributing conduit.

In the drawings:

Figure l is an axial sectional view of the preferred embodiment of myinvention.

Fig. 2 is a top view partly in section, the section being taken on theline A-A of Fig. 1.

Figs. 3 and 4: are views of the valve used for regulating thegrease-cup.

Referring to the aforesaid drawings, is the foot or stem of the greasecup. The foot is bored in the direction of its axis as shown at Z) toprovide a chamber to receive a tube c. The tube is formed of cervinite,a substance similar to Celluloid, but practically unbreakable,uninflammable and transparent. Said tube may be seen through lateralapertures provided in the foot. A passage e conveys the oil to themember to be lubricated. Tube c is kept in its position by a threadedplug f 1920. 'serial No. 378,345.

having a nozzle gl which extends into the tube aand' forms a droppingdevice for the lubricating mixture. Y

The upper portion o-f the foot isprovided f formsa reservoir for theoil.A lid is se- 15e? cured lto the upper end of said tubehand is connectedwith a tube y' which extends downwardly through` the whole grease-cupAbody and" has its lower end seated in the plug f.

Within said tube y' is a stem lcgriveted to a cirular cover Z they'outer periphery of which is `knurled to provide a hand. engagingsurface and the inner periphery ofwhich is corrugated so as to formkey-grooves within which operates a spring In, fixed to the lid z'. Saidgrooves and spring will allow of stopping the cover Z, and the stem Zowhen in a certain position relatively to the grease-cup itself. Thelower end of stem 7c is provided with a finger 0` eccentric-allydisposed respectively to the axis of said stem 7c and bearing againstthe end of a conical flap-valve p' which is seated in a taper openingprovided in tube y'. Said flap-valve p is forced towards its seat bymeans of a spring g which engages a notch in the head of said'flap-valve.

When the outer cover Z is turned, a finger o of stem 7c forces theflap-valve outwardly` away from its seat. The oil may thereafter iow insmaller or larger quantity into the nozzle g of the grease-cup and falltherefrom into the tube e from which it passes to the lubricatingmember. The position of the finger relatively to the valve, i. e. to theopening of the latter may be indicated by means of figures engraved onthe upper surface of the lid z' which appear through an opening providedin the outer cover Z. Saidv opening is also used for lling thegreasecup, asv it may be brought into alignment with an aperture of likedimension provided in the lid z'. Y

I claim:Y l y 1. A grease cup comprising a body portion provided with alubricant outlet, a tube located within the body and communieating withsaid outlet, a valve arranged in the lower part of said tube and havinits axis arranged at right angles to the axis ofv said' tube, and meansincluding an element pendicularly to the axis of said tube, andy meanscontrolled from the exterior of the body portion and' extending within'said tube for controlling said valve.

'8. A grease cup comprising a tubular body providedr with a lubricantoutlet, a tube-arranged within the body portion and providednear'itslower end with an aperture, a `iap-valve controlling' said aperture andhaving its axis intersectin the axis of the tube, a stem arrangedv witin the tube and'provided with aneccentrically arranged iinger'designedto engage said valve for controlling the opening'of the same,jand meanslocated on the exterior of thebody for controllingmovements of saidstem.

4; A device of the-kind defined bly/.claim 3 in-'Which means areprovided for closing said valve, said means comprising a spring engagingthe tube and the valve.

5. A grease cup including a tubular body provided with a lubricantoutlet, a tube located in the body, a valve arranged' in the tube,avalveoperating stem located in the Y tube and engaging saidV valve, alid orsaid body provided with indicating marks, a

spring carried by said lid and projectin through one sideof the same, acover fixe to said stein and overlying said lid, said cover beingprovided with spaced notches detachably engaged by said springA and anaperture in the cover for observing said indicating marks. f

6. A lubricating devicev of vthe kind 'de-` fined by claim 5 in which4thelid is provided with an aperture iadaptedto cooperatewith theaperture of saidjco-ver Vfor filling-the body. Y Y
